A novel ultra-stable metal–organic framework, MCIF-1, [Cu2(DCI)2](MeCN), based on dicyanoimidazole and Cu(I), has been synthesized at room temperature successfully. MCIF-1 shows excellent water stability and can retain crystallinity after soaking in water for about one week. In addition, MCIF-1 also shows exceptional resistance under both acidic and basic conditions within a large pH range from 0 to 13.5. What is more, after modifying the synthesis procedure slightly, we can produce this material in a large scale during a very short time. Mild synthesis conditions, excellent stability and ease of large scale production give MCIF-1 great potential for practical use.

The large-scale preparation of fluorescent nanomaterials with laboratory-relevant chemical and optical properties will greatly forward their consumer market applications; however, it still remains challenging. In this work, a universal strategy was developed for the rapid and large-scale synthesis of fluorescent sulfur quantum dots that recently has drawn great attention because of their unique optical characteristics. From the fact that empty 3d orbitals of sulfide species are able to bind with lone-pair π electrons of the heteroatomic groups, many amino-group containing compounds, such as amino acid and polyethylenimine molecules, were exploited to synthesize sulfur quantum dots. This 10 min preparation period endowed sulfur quantum dots with bright blue fluorescence and also chirality. Due to the user-friendly and rapid operation, this strategy can be extended to the large-scale synthesis of sulfur quantum dots with a yield of 16.844 g for one batch of experiment. Moreover, it was found that the sulfur quantum dots exhibited a reversible temperature-dependent luminescent property with a sensitivity of 0.72%/°C, which showed excellent intracellular temperature monitoring capability for inflammation-related disease diagnostics.

Analcime (ANA) crystals have wide applications in the field of selective adsorption, nanoelectronics, light gas/hydrocarbon mixture separation, and radioactive element adsorbents. However, many organic templates were necessary to synthesize ANA crystals in previous work, causing significant environmental pollution and high cost. Thus, it is crucial to synthesize single ANA crystals under a simple system without the organic template. Herein, we explore the synthesis of large single ANA crystals (size up to 210 μm) in the template-free system of SiO2 : 0.274Al2O3 : 1.79Na2O : 190H2O at 180 °C for 40 h. The absence of expensive organic templates and hydrofluoric acid (HF) dramatically reduces the costs and pollution. This makes the method more conducive to mass production. Meanwhile, we report a series of growth conditions for ANA crystals with different sizes, which is more conducive for the preparation of the required ANA single crystals for different application scenarios.

A low cost and large scale synthetic approach was developed for colloidal PbS quantum dots (QDs). The heat up strategy was adapted for large scale production, thioacetamide in oleylamine (OLA) was used as the sulphur precursor for low cost and safe synthesis, and PbCl2 in OLA was used as the lead precursor for a well passivated surface. Due to the balance between the diffusion coefficient and monomer oversaturation generated by the dissolution of small particles, an optimum growth temperature exists in the new synthesis. The synthesis was easily scaled up to produce 18 g of PbS QDs from one reaction batch, with a high chemical yield of ∼80% and the as synthesized QDs exhibit a high photoluminescence quantum yield of >40% and excellent air-stability of at least 60 days, due to the Cl− and oleate co-passivation.

A convenient route for the synthesis of a third-generation epidermal growth factor receptor inhibitor, mereletinib (AZD9291) using starting materials that are commercially available has been achieved through reactions that are readily conducted under mild conditions. Importantly, a 5 g scale synthesis was also accomplished and this method could therefore be useful in the synthesis of similar drugs.

Large-scale production of full-color carbon dots (CDs) at room temperature under atmospheric pressure will promote their industrial application. Herein, o-phenylenediamine is used as a single-precursor carbon source and hydrogen peroxide as an oxidant. Kilogram-scale CDs are obtained by stirring these reactants at room temperature in air for 30 min. After purification and acid treatment, blue-, green-, and red-fluorescence CDs with photoluminescence peaks at 481, 539, and 625 nm are obtained with quantum yields of 21.76%, 27.12%, and 13.06%, respectively. Based on chemical structural characterizations, a reasonable formation mechanism is deduced, with blue, green, and red fluorescence arising from carbon nuclei stacked in conjugate planes containing fragments of quinoxaline, 2,3-diaminophenazine (2,3-DAPN), and protonated 2,3-DAPN, respectively. High-quality multi-color and white light-emitting diodes are successfully fabricated to demonstrate potential commercial applications in display and illumination.

Due to their compactness, storage/supply flexibility, modularity and factory manufacturability, batteries are excellent candidates for large scale energy storage applications . However, the widespread application of most batteries hitherto developed is hindered by their high cost. Here, an intermediate temperature molten salt battery is developed that emphatically resolves this issue by using all earth-abundant and cheap elements. Operated at 170 °C, the cell comprises of an Fe metal anode, NaCl saturated NaAlCl 4 electrolyte and an AlCl 4 − intercalated graphite cathode in the fully charged state. It has a capacity retention of 85% after nearly 10,000 cycles. After characterizing the anode, it was determined that the high reversibility of the Fe to FeCl 2 solid state transformation are responsible for the absence of dendritic growth on such a metal anode. Different electrode capacity matching strategies are discussed in the context of ensuring safe operation during overcharging. Finally, the overall material cost of the Fe/Graphite cell is estimated to be 33.9 $ kWh −1 , which can potentially meet the demands of the commercial energy storage market.

Mass production of graphene with low cost and high throughput is very important for practical applications of graphene materials. The most promising approach to produce graphene with low defect content at a large scale is exfoliation of graphite in an aqueous solution of surfactants. Herein, we report a molecular design strategy to develop surfactants by attaching ionic groups to an electron-deficient π-conjugated unit with flexible alkyl spacers. The molecular design strategy enables the surfactant molecules to interact strongly with both the graphene sheets and the water molecules, greatly improving graphene dispersion in water. As the result, a few-layered graphene concentration as high as 1.2–5.0 mg mL–1 is demonstrated with the surfactant, which is much higher than those (<0.1 mg mL–1) obtained with normal aromatic or nonaromatic surfactants. Moreover, the surfactant can be easily synthesized at large scale. The superior performance and convenient synthesis make the surfactant very promising for mass production of graphene.

Na-ion batteries (NIBs) have received significant interest as potential candidates for large-scale energy storage owing to the widespread distribution of sodium and superior low-temperature performance. However, their commercial application is usually hindered by the high production cost and inadequate performance for electrode materials, particularly for cathodes. Na3(VOPO4)2F (NVOPF) has been recognized as one of the most promising cathodes for high-energy NIBs owing to the high working voltage and energy density. Here, we report a facile highly efficient room-temperature solution protocol for large-scale synthesis of NVOPF cathode for NIBs. By simply regulating pH, NVOPF can be obtained, which delivered a discharge capacity of 120.2 mAh g-1 at 0.1 C and 72% capacity retention over 8000 cycles at 25 C. Besides, the kilogram-level NVOPF products have been synthesized, and 26650 cylindrical cells were fabricated, which exhibit excellent cycling stabilities, remarkable low-temperature performance with comparable safety features. We hope our findings could provide insights on the industrial application of NVOPF in NIBs.

In this study, we report a large-scale and facile synthetic method for silver nanoparticles via a microwave method, which is quite time-saving and efficient. The obtained silver nanoparticles maintained a uniform size, and the average size was less than 20 nm although the concentration of the silver source was very high. The obtained silver nanoparticles could be homogeneously dispersed in deionized water, which was beneficial for the fabrication of the conductive ink. For large-scale industrialization, the synthetic process window was widened to a great extent via a series of experiments. We injected the ink into a blank mark pen to fabricate a conductive pen, via which the tracks drawn on the photo paper could immediately become conductive at room temperature with an electrical conductivity of 2.4 μΩ cm (about 1.5 times that of the bulk Ag). The mechanical properties of the tracks were examined for a twistable application. After bending at a radius of 4 mm and 2 mm for 5000 circles, only a slight increase in their resistance of 1.20 and 1.78 relative to their initial resistance, respectively, was observed. The as-prepared conductive ink and fabricated pen have potential applications in flexible electronics.

Industrial electrolysis of water is one of the effective strategies for green hydrogen production in the future. Nevertheless, the large-scale applications of water electrolysis are still intractable issues hindered by the high overpotentials and inferior reaction kinetics on the anode. Herein, a facile one-step hydrothermal method was applied to in situ growth the Fe and V co-doped Ni 3 S 2 electrocatalyst on nickel foam substrate (Fe, V–Ni 3 S 2 /NF). In 1 M KOH electrolyte, the as-prepared Fe, V–Ni 3 S 2 /NF electrode exhibited an improved water oxidation activity with ultralow overpotentials of 253 and 370 mV to realize large current densities of 100 and 1000 mA/cm 2 , respectively. More importantly, the Fe, V–Ni 3 S 2 /NF electrode existed an activation process during 100 h chronopotentiometry testing period. Detailed characterizations revealed that elements of V and S in the electrocatalyst were oxidized and dissolved into the electrolyte, making the electrocatalyst undergo surface reconstruction and resulting in a faster kinetic reaction rate, thus leading to enhanced oxygen evolution reaction activities. Collectively, the resultant Fe, V–Ni 3 S 2 /NF in this work provides new cogitation towards design and synthesis of low-cost electrocatalyst with large current densities for water oxidation.

Rechargeable hydrogen gas batteries are highly desirable for large-scale energy storage because of their long life cycle, high round trip efficiency, fast reaction kinetics, and hydrogen gas profusion. Coupling advanced cathode chemistries with hydrogen gas anode is an emerging and exciting area of research. Here, a novel high-performance aqueous iodine-hydrogen gas (I 2 -H 2 ) battery using iodine as cathode and hydrogen gas as the electrocatalytic anode in environmentally benign aqueous electrolytes is reported. The working chemistry of the battery involves I 2 /I − solid-liquid reactions occurring over the cathode along with H 2 /H 2 O gas-liquid reactions at the anode, achieving a high rate performance of 100 C and long-lasting stability of over 60 000 cycles. Additionally, the static aqueous I 2 -H 2 battery displays a volumetric capacity of 15.5 Ah L −1 along with good self-healing capability towards cell overcharge. The current battery design exhibits robust electrochemical performance irrespective of acidic, neutral, and alkaline electrolyte systems. This study paves the way towards the industrialization of economically effective, high-power density, and long-term I 2 -H 2 batteries for large-scale energy storage applications.
